Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

Laser &Photonics Reviews, EarlyView.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Digital phase locked loop

ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
This paper deals with the design, construction and evaluation of a Digital Phase-Locked Loop. An exclusive OR gate serves as a linear phase detector. The integrator consists of a cascade of up/down decade counters. The D.C. value of each cycle from the phase detector is measured and accumulated. The rate of integration is determined by the clock input.

A Fast-Locking Digital Phase-Locked Loop

Third International Conference on Information Technology: New Generations (ITNG'06), 2006
A conventional digital phase-locked loop (DPLL) is designed using (Baker et al., 2003) to operate at 1GHz using 0.18 mum CMOS technology; its lock time is 4.19 mus. By adding a coarse/fine tuning control unit composed of a digital-to-analog converter (DAC) and a counter as well as switching the currents of the charge pump, a fast-locking DPLL results ...
